1 Alcatel-Lucent 7750 Service Router

2 The Alcatel-Lucent 7750 Service Router (SR) is the industry s first service router designed and optimized for the delivery of high-performance carrier data, voice and video services. The Alcatel-Lucent 7750 Service Router was designed with system characteristics, routing and service capabilities that have made it the platform of choice in more than 50 newgeneration service infrastructure rollouts. 2 Alcatel-Lucent 7750 Service Router

3 The Changing Service Landscape Rethinking the Service Delivery Architecture The Alcatel-Lucent 7750 SR functions as both a powerful router and a flexible service delivery platform, and integrates with the Alcatel-Lucent 5620 Service Aware Manager (SAM) to deliver efficient and streamlined provisioning, management and billing for Internet protocol (IP)/multiprotocol label switching (MPLS) networks. Global service providers are preparing for the next wave of residential and business service deployments. They understand that in order to be successful they need a service delivery infrastructure that offers more bandwidth, delivered flexibly and reliably to more customers simultaneously, with increased service level guarantees. Service providers are increasingly called upon to offer personalized voice video and data services that recognize the unique needs of individual users; that are, in other words, more user-centric. While the past few years have seen a focus on network and service convergence with an emphasis on killer applications delivered over a single infrastructure, the paradigm has shifted to a user-centric focus that embraces the demand for a customized and media-rich user experience across multiple access methods and across applications. For the residential market, the need to deliver broadcast TV and video-ondemand (VoD) services that meet high service level agreement (SLA) standards has introduced an inflection point that has pushed network service providers to profoundly rethink their service delivery architectures. High-speed Internet (HSI) infrastructures were built around inefficient business models that focused on cost-persubscriber considerations and allowed for significant oversubscription and service level leniency. New high-sla voice and video applications have very stringent availability, system characteristics, quality of service (QoS), multicast and service requirements. Those requirements can only be cost-effectively addressed by rethinking the overall service delivery infrastructure. Alcatel-Lucent 7750 Service Router 3

4 In the enterprise space, new managed data services such as virtual private LAN service (VPLS), IP virtual private networks (IP-VPNs) and multiservice transit applications using pseudowires (PWs) over a variety of access methods (frame relay [FR], asynchronous transfer mode [ATM], Ethernet, high-level data link control [HDLC]/point-to-point protocol [PPP], etc.) allow service providers to attract and retain a wider customer base at a lower cost through converged and more reliable IP/MPLS service infrastructures. In turn, end-user customers benefit from a wider variety of service offerings, increased service flexibility and accelerated service activation. With the Alcatel-Lucent 7750 SR, service providers are able to build a new type of cost-optimized highly-available and featurerich service delivery infrastructure that can seamlessly scale to address both residential and managed data service market needs, while delivering significant economies of scale, skill and scope.

5 A New Class of Platform The Alcatel-Lucent 7750 SR platform provides purpose-built, highly available software and hardware architectures that allow network operators to right-size their service infrastructure buildout. The 7750 SR provides the necessary built-in services capabilities and packet processing headroom to allow service providers to scale service instances, subscriber count and bandwidth without incurring exponential capital or operating expenditures (CAPEX or OPEX). The critical features and functions that differentiate the Alcatel-Lucent 7750 SR from a typical Internet-era edge router are the system characteristics (delay/jitter) and service-related capabilities that were tightly integrated into the product architecture at inception. The change from traditional best-effort Internet routing and enterprise switching to true service routing is not an incremental step it is a radical advancement that has required a complete rethinking of the product architecture and design at inception. This inflection point is where the Alcatel-Lucent 7750 SR has established a leadership position. An Industry First The challenges that service providers are facing have evolved from addressing rampant bandwidth growth for Internet traffic to enabling cost-optimized and highly resilient service delivery infrastructures that can scale and ensure profitability while minimizing the overall deployment risk in the long run. Existing Internet-era routers and enterprise switches were designed five to eight years ago to handle bandwidth growth for best-effort traffic. These platforms were not optimized for new-generation service infrastructure rollouts, as they are limited by their system characteristics (delay/jitter, packet re-ordering and loss) and their inability to scale services across all dimensions (number of interfaces, bandwidth, service instances and policies, performance level, etc.). Similarly, so-called IP service platforms have appeared on the market, but they were designed and optimized for low-speed, besteffort consumer services (mass-market digital subscriber line [DSL] for residential service). They do not have the high-availability, scalability or service capabilities that will allow them to cost-effectively enable largescale (tens of millions of customers), highspeed data, voice and video service rollouts.

6 The Profitability Factor An improved regulatory environment and the clear potential for incremental revenue have convinced many incumbent service providers to rapidly make considerable investments in new service delivery infrastructures. By adding video, voice and managed data services to their existing highspeed data and Internet service lineups, service providers can improve their competitive position in the market. All service providers competing in this market are faced with the challenging task of offering a compelling value proposition for their service offerings in order to achieve and maintain a high average revenue per user (ARPU) and to sustain the long-term profitability of their services (see Figure 2). For service providers who successfully meet this challenge, benefits will include the ability to: Successfully sell new, higher value services to their established customer base Leverage their brand equity to offer highmargin bundles and minimize churn Progressively build their service infrastructures around profitability models, as opposed to network or infrastructure constraints Consolidate multiple specialized networks into a cost-optimized and efficient service infrastructure that will achieve economies of scale and maximize the profitability of services Figure 2 - Projected ARPU for Various Triple-Play Services 200 HDTV DVR ARPU (in U.S. Dollars) VoD Premium Video Digital Video Basic Video Broadband Long Distance 0 Voice Only Voice and Data Voice, Video and Data Local Source: The Yankee Group, Alcatel-Lucent 7750 Service Router

7 Streamline network operations across protocol layers to achieve economies of skill, and evolve the overall service infrastructure to a more homogeneous, scalable and flexible architecture Streamline business operations to achieve significant economies of scope across service offerings (e.g., order fulfillment, support, billing, marketing) Future-proof their service infrastructures for the future layering of ultra-high bandwidth business and residential applications Minimize the overall financial and technological risks over the next seven to ten years In order for service providers to achieve significant economies of scale, skill and scope they need to evolve their second-mile, and perhaps first mile, infrastructures to a highly available, secure and cost-optimized service delivery foundation that can scale to support existing and future ultra-high-speed residential and business service rollouts. This requires a comprehensive approach to the service delivery architecture design. The Alcatel-Lucent 7750 SR offers unmatched density and performance: up to 400 Gb/s full duplex redundant capacity in one-third of a carrier s system rack. This, along with its advanced service-oriented features, makes it the ideal choice for service providers who are looking to roll out a new generation of triple-play infrastructure-based services. An important capability that distinguishes the Alcatel-Lucent 7750 SR from Internetera routers is the built-in packet processing, service headroom and flexibility that ensures that new features can be soft-loaded with the promise of uncompromised performance up to 40 Gb/s per slot. Application-specific integrated circuit (ASIC)-based implementation, on the other hand, requires a costly and lengthy line card re-spin each time a new feature or extension is required. For the service provider this results in high cumulative CAPEX, disruption of service and slot exhaustion as each new feature and capability requires a new specialized line card or module. This approach lengthens time-to-market for services and introduces significant support and turnaround time. The Alcatel 7750 SR is a great example of a multiservice edge router. It not only combines the scalability that s required for these consolidated IP/MPLS networks, but it also incorporates a number of different features that help service providers deliver IP/MPLS-based services. That is really the distinguishing factor between the 7750, for example, and some other traditional edge routers on the market today. It makes it a great fit for those consolidated network environments.

11 Service-Based Accounting Instead of maintaining statistics on a per-port basis, the Alcatel-Lucent 7750 SR keeps statistics on a billable service basis, providing accurate measure ment of each customer s traffic and each individual service s confor - mance to the offered SLA. Service-Based Filtering The Flexible Fast Path technology of the Alcatel-Lucent 7750 SR enables service providers to define and apply complex filters without performance impact, providing high levels of security and troubleshooting on a per-service basis, even at 10 Gb/s speeds. Global templates allow complex functions to be defined once and applied to individual ports or services as required. Service-Aware Operational Toolkit A key feature of the Alcatel-Lucent 7750 SR is its comprehensive set of service-aware tools that allow efficient operation, administration, maintenance and provisioning (OAM&P) of IP/MPLS networks and, more importantly, services. The Alcatel-Lucent 7750 SR supports a variety of protocols and custom-designed tools to help service providers verify correct operation on a per-service basis and trouble - shoot individual services should an issue arise, without the need for complex scripting and command line debugging of individual routers. In addition to extensive service assurance and diagnostic tools, the Alcatel-Lucent 7750 SR supports a unique service mirroring function that mirrors traffic on a per-service or sub-interface basis, and re-encapsulates the mirrored data for transport through the core network. This enables an operator to see the actual traffic from any customer s service at a central network opera tions center, reducing The Alcatel 7750 SR is a new category of platform that exceeds the requirements we have developed with the help of service providers. We are comfortable validating the Alcatel 7750 SR s overall state-of-the-art routing and Layer 2 and Layer 3 service capabilities, and are confident the product will allow service providers to activate a new generation of high-performance IP-based services.

13 Three Scalable Chassis Options One Industry-Leading Solution The Alcatel-Lucent 7750 SR delivers outstanding performance, flexibility and scalability across a range of services, leveraging a generational leap in technology compared to today s Internet routers. The Alcatel-Lucent 7750 SR has three chassis options: 12-slot, 7-slot and 1-slot. These chassis options incorporate the latest technology to offer carrier-class reliability and industry-leading throughput and density in an efficient, compact footprint. Modular Design The modular chassis design scales from 20 Gb/s to 400 Gb/s (full-duplex) with a very small footprint, addressing a range of service appli cations from small points of presence (PoPs) to collapsed core applications. This ability to scale down services allows network operators to right-size their CAPEX invest - ment, yet provides them with the necessary processing headroom that allows them to scale service instances, subscriber count and bandwidth without compromise. The common design features of the three chassis help to reduce capital and operating expenses. SR-1 SR-7 Interchangeable I/O modules, media depend - ent adapters and a common operating system across all three platforms further reduce both capital and operating expenses.
